Adaptive methods for robust commercial vehicle control

Creator:: Junell, Jaime L.
Abstract:: This thesis explores the implementation of learning based control with predictive cruise control and the potential this technology has for increasing fuel efficiency while keeping on a well maintained schedule for commercial trucks. Traditional cruise control is wasteful when maintaining a constant velocity over rolling hills. Predictive cruise control is...

The geometric characterization and thermal performance of a microchannel heat exchanger for diesel engine waste heat recovery

Creator:: Yih, James S.
Abstract:: Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...

An experimental study of flow boiling heat transfer enhancement in minichannels with porous mesh heating wall

Creator:: Wang, Hailei
Abstract:: A unique channel surface enhancement technique via diffusion-bonding a layer of conductive fine wire mesh onto the heating wall was developed and used to experimentally study flow boiling enhancement in parallel microchannels. Each channel was 1000 μm wide and 510 μm high. A dielectric working fluid, HFE 7000, was used...

Interactions of a fully modulated inclined jet with a crossflow

Creator:: Dano, Bertrand P. E.
Abstract:: Jets in crossflow are used in a wide range of engineering applications and have been studied for more than 60 years. The transversal penetration and structure of a jet placed in a crossflow is known to be strongly three-dimensional. It is believed that, by using a pulsed jet inclined in...

Optimizing ballast design of wave energy converters using evolutionary algorithms

Creator:: Colby, Mitchell
Abstract:: Wave Energy Converters (WECs) promise to be a viable alternative to current electrical generation methods. However, these WECs must become more efficient before wide-scale industrial use can become cost-effective. The efficiency of a WEC is primarily dependent upon its geometry and ballast configuration which are both difficult to evaluate, due...

Coevolution and transfer learning in a point-to-point fleet coordination problem

Creator:: Yliniemi, Logan Michael
Abstract:: In this work we present a multiagent Fleet Coordination Problem (FCP). In this formulation, agents seek to minimize the fuel consumed to complete all deliveries while maintaining acceptable on-time delivery performance. Individual vehicles must both (i) bid on the rights to deliver a load of goods from origin to destination...

Enabling safety-informed design decision making through simulation, reasoning and analysis

Creator:: Jensen, David Charles
Abstract:: While many organizations claim to "put safety first," safety is rarely considered early in the design process when system-level architectural decisions are made. Instead, system design follows an abstraction-to-detail process to first meet functional and then performance requirements. Following this process, safety assurance occurs in the later stages of design...

Modeling, control, and estimation of flexible, aerodynamic structures

Creator:: Ray, Cody W.
Abstract:: Engineers have long been inspired by nature's flyers. Such animals navigate complex environments gracefully and efficiently by using a variety of evolutionary adaptations for high-performance flight. Biologists have discovered a variety of sensory adaptations that provide flow state feedback and allow flying animals to feel their way through flight. A...

The effects of pulsing and blowing ratio on a 45° inclined jet in cross flow

Creator:: Stander, Arjan
Abstract:: The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...
